From Lab to Market: Accelerating Next Generation Battery Development with Plasma FIB-SEM and TOF-SIMS Workflows

Electrochemical materials in battery designs and research on them are critical in achieving a sustainable energy future as well as energy independence from fossil fuels.

In practice, energy density, cell longevity, and charge rate are bonded to chemical composition and specific structural features within the batteries. In general, optimization of all these parameters is a multiscale, multimodal challenge that consists of the analysis of the anode, cathode, electrolyte, and their interphases.

This talk introduces the role of a Scanning Electron Microscope equipped with a Focused Ion Beam (FIB-SEM) uniquely combined with a compact Time-of-Flight Secondary Ion Mass Spectrometer (ToF-SIMS) in the characterization of the morphology and chemical composition of Li-ion batteries interphases. We will specifically focus on how SEM observation with ToF-SIMS and other analytical techniques such as Energy Dispersive X-ray spectroscopy (EDS) can be used to better understand and evaluate characteristics such as degradation of battery material, SEI formation, or chemical phase change within the battery cell.
